Abstract: An improved method for aromatizing soluble coffee is described which results in a higher fixation of grinder gas aromas on a glyceride substrate and an improved quality jar aroma. The method involves liquid-liquid contact of the water phase, normally drained from equilibrated grinder gas and discarded, with a glyceride to recover valuable coffee aromatics in the glyceride. Further, reflux of liquid carbon dioxide is used to recover yet more valuable coffee aromatics in the glyceride. A 25 to 70% increase in aromatic yield is realized with an improvement to the aromatic quality of the aromatized glyceride and thereby the aromatized soluble coffee.

Abstract: In this process and this device, air and/or pure oxygen is passed into the waste water in an aeration tank in the presence of biomass which is immobilised on carrier particles, and the waste water is subsequently separated into purified water and activated sludge in a secondary sedimentation. Since the biomass in the core of the carrier particles dies off gradually, the invention provides acceleration and slowing-down devices which allow regeneration of the carrier particles. In this process, the carrier particles are accelerated and then slowed down, so that according to the kinetic energy which is set free, a compression of the carrier material in some parts and therefore a loosening and partial elimination of the dead biomass are achieved. The biomass concentration in the carrier particles can be controlled by changing the speed at which they leave the accelerating zone. (Figure) <IMAGE>

Abstract: In accordance with the present invention, specific binding assays are disclosed which utilize an chemiluminescent compound, i.e., moiety, which has increased stability in aqueous solution. The chemiluminescent moiety is an ester, thioester or amide in which the ester, thioester or amide linkage is between (1) a heterocyclic ring or ring system containing a carbon atom to which the linkage is attached, wherein the heteroatom within the heterocyclic ring or ring system is in an oxidation state which renders such carbon atom susceptible to attack by peroxide or molecular oxygen to form an intermediate which decays to produce chemiluminescence, and (2) an aryl ring or ring system. The aryl ring or ring system contains at least one substituted six-member ring. The substituted six-member ring has two or more substituent groups, where at least two of said two or more substituent groups sterically hinder hydrolysis of said linkage. One or more of the substituent groups which sterically hinder hydrolysis of said linkage may be an electron withdrawing group. The substituted six-member ring may have one or more additional substituent groups in addition to the substituent groups which sterically hinder hydrolysis of the linkage.
